And is this right???: cubed root of X^5y^5= (x^5y^5)^1/3=x^5/3y^5/3=(xy)^5/3

Thanks for your excellent help

Hi JoanneMac,

It is hard to tell what was the original problem. Are you sure all your parentheses are where they are supposed to?
In other word, do you really mean ? which is .
Or do you mean (-x^(2y^2))/(x^(1/2y^0))? Which is .
Or something else?
